Question
Design a software system that simulates a real world system (such as ATMs, banks, courses, games...). The program (the software system) must contain selection (if), repetition (loop), methods, user DEFINE class, and arrays. The documents include flowchart, UML, and comments in the program. You have to present your program (demonstration and explanation) on 11//28/2016 This program is 130 points (100 + 30 presentation). 2D arrays Relate classes through inheritance or composition. Design the system to perform more functions.Explanation / Answer
public class AtmMachine {
Scanner input;
int[] validId;
Atm createOne;
// AtmMachine constructor
AtmMachine() {
input = new Scanner(System.in);
createOne=new Atm();
validId = new int[10];
}
void performOperations() {
int choice;
double withdraw,balance;
for(int i=0; i<validId.length; i++){
//Prompt user to enter the identification number(ID)
System.out.print("Enter an id: ");
validId[i]=createOne.setId(input.nextInt());
//Prompt user to enter the correct identification number(ID)
while((validId[i]<0)||(validId[i]>9)){
System.out.println(" Invalid id! Please enter your id again.");
System.out.print(" Enter an id: ");
validId[i]=createOne.setId(input.nextInt());
}
while(true){
displayMenu();
//Prompt user to enter the choice
System.out.print("Enter a choice: ");
choice=createOne.setChoice(input.nextInt());
balance=createOne.getBalance();
//Display the choice results
switch(choice){
case 1:System.out.println(" The balance is "+balance);
break;
case 2:System.out.print(" Enter an amount to withdraw: ");
withdraw=createOne.setWithdraw(input.nextDouble());
if(createOne.setBalance(balance)>=withdraw){
createOne.getWithdraw();
}
else{
System.out.println(" Not enough balance. Balance is "+createOne.setBalance(balance));
}
break;
case 3:System.out.print(" Enter an amount to deposit: ");
double deposit=createOne.setDeposit(input.nextDouble());
createOne.getDeposit();
break;
case 4:System.out.print(" Enter an id: ");
validId[i]=createOne.setId(input.nextInt());
while(validId[i]<0||validId[i]>9){
System.out.println(" Invalid id! Please enter your id again.");
System.out.print(" Enter an id: ");
validId[i]=createOne.setId(input.nextInt());
}
break;
case 5: return;
default:System.out.println(" Invalid selection. Please select your choice again.");
}
}
}
}
private void displayMenu() {
//Display the main menu
System.out.println(" Main menu ");
System.out.println(" 1:check balance ");
System.out.println(" 2:withdraw ");
System.out.println(" 3:deposit ");
System.out.println(" 4:exit ");
System.out.println(" 5:logout ");
}
/**This program is created to simulate an ATM Machine.
main method*/
public static void main(String[] args) {
AtmMachine am = new AtmMachine(); // line 1
am.performOperations(); // line 2
} // <---- that's it !!!
}
